Description

Got inspiration from all the different 3D printed prosthetic hands and was thinking my conductive TPU rubberlike filament could add a dimension or 2...
This dualstrusion will create the finished finger with joints and a force sensitive fingertip. The fingertip has a outer shell that, when pressed, will connect to the inner conductive surface, thus creating a closed circuit.
This model is only a quick proof of principle design... and the picture of a full hand is only a visualization of a hand that could be printed in one go... perhaps!? Are you up for the challenge?
The smudging of the conductive material resulted in a closed loop at aprox 8.5k and when pressing the tip it goes down to 7.2k
Its my first dualstrusion, I used 0.7mm nozzles and I could for sure need to adjust the height of the nozzles and it would be great to have retractable nozzles to get rid of the smudging...
I designed the finger in a straight shape but it would be better to print it bent outwards, the TPU material has a problem to bend the finger all the way back after it has been closed lots of times... or change the shape of the joints...
